<h3><u>Answer</u>;</h3>

A. Pressure causes water and dissolved substances to filter through capillary walls of the glomerulus.

<h3><u>Explanation;</u></h3>
  • <em><u>During filtration the flow of blood in the glomerulus creates hydrostatic pressure in the glomerulus which forces molecules through the glomerular filtration membrane. </u></em>
  • Normal filtrate contains of water, glucose, amino acids, urea, creatinine, and solutes such as sodium chloride, calcium, potassium and bicarbonate ions.

How does seed formation take place in plant? explain.​
neonofarm [45]

Answer:

Seeds are the result of plant reproduction. ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.

Sex-Related inheritance: X chromosome; Non Sex-Related inheritance​
ser-zykov [4K]

<u>What we already know:</u>

All species under normal circumstances will have two sex chromosomes. X and Y, Y is known to be dominant. All females will have two X chromosomes (XX, one X will always be given by the mother), whereas males will have one Y chromosome and one X chromosome (XY, one X will always be given by the mother. The father, on the other hand, could give either an X or a Y, that all depends on what sex chromosome the father's sperm donated.)

<em>So, how many chromosomes do a typical human have? Correct, a typical human has 32 chromosomes and only 2 of them are sex chromosomes. Now we must understand that the sex chromosome carries more than just the one code for the individual sex</em>.<em> That means that the gene codes for more than just the sex. </em>

<u>Building on that knowledge: </u>

<em>Sex-Related Inheritance</em> that differs from sex, is carried on one or two of an individual's sex chromosome. Whereas <em>Non-Sex-Related Inheritance</em> is carried on the other thirty chromosomes that the individual also carries.

<em>Sex-Related</em> inherited genes that are passed via the father to male offsprings, carried on the Y chromosome, are easiest to spot in a family. All males will have this trait and no females will.

Non-sex-related inheritance can be passed from male to female and from female to male, this is sometimes harder to differentiate from genes carried on the X chromosome because the mother always gives an X chromosome.

<u>Vocabulary:</u>

phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

After being produced, ________ provides the blueprint for assembling proteins
eduard
The mRNA molecule is the blueprint for protein assembly in the processes described in the central dogma of molecular biology.
The process of translating the information in DNA to proteins happens in three steps.
Firstly, the DNA molecule replicates itself. 
After that one DNA strand (DNA is a double-stranded molecule)  transcribes itself into one-stranded messenger RNA (mRNA).
The information is held in the sequence of the nucleotides (Adenine, Cytosine, Guanine, Thymine) and it is read in triplets. So each mRNA is made from a sequence of nucleotides copied from the DNA, that is read in triplets.
Each triplet is holding the information about a specific amino-acid carried by transporter RNA (tRNA).
Proteins are made in the ribosomes in the process of translation, where the sequence on the mRNA is being read and translated into a sequence of amino acids.
